    from awsglue.transforms import *
    from awsglue.utils import getResolvedOptions
    from pyspark.context import SparkContext
    from awsglue.context import GlueContext
    from awsglue.job import Job
    glueContext = GlueContext(SparkContext.getOrCreate())

13. Learn the publicly accessible Medicare Supplier fee information within the AWS Glue information preparation pattern doc:

    medicare_dynamicframe = glueContext.create_dynamic_frame.from_options(
        's3',
        {'paths': ['s3://awsglue-datasets/examples/medicare/Medicare_Hospital_Provider.csv']},
        'csv',
        {'withHeader': True})
    print("Rely:",medicare_dynamicframe.depend())
    medicare_dynamicframe.printSchema()

14. Change the information sort of the supplier ID to lengthy to resolve all incoming information to lengthy:

    medicare_res = medicare_dynamicframe.resolveChoice(specs = [('Provider Id','cast:long')])
    medicare_res.printSchema()

15. Show the suppliers:

    medicare_res.toDF().choose('Supplier Title').present(10,truncate=False)

Clear up

You’ll be able to run %delete_session which deletes the present session and stops the cluster, and the person stops being charged. Take a look on the AWS Glue interactive periods magics. Additionally please bear in mind to delete IAM coverage and function as soon as you might be executed.
